Photography

Photography by this instrument is classiﬁed into non-mydriatic/mydriatic color, mydriatic ﬂuorescein photography. It
is recommendable to grasp a rough operations’ ﬂow along the purpose of each photography. If malfunction should
occur on this equipment, an alarm will buzz.

Besides this classiﬁcation of photography, photography of enlarged image, small pupil, LCDmonitoring and infrared
photography (when optional ﬁlter is mounted) are also available. It is also possible to record hand-written data into
35-mm ﬁlm. For more information about the method, see items of “4 Other practical photography” described below.

• It takes about three seconds to switch to a desired photography mode.
Since photographing immediately after switching the mode does not allow you to capture a good image, wait

at least three seconds before starting photography.
